PRD Secondary Density Bonus. In order to achieve the maximum PRD density, an applicant must utilize the primary and secondary density bonuses.
For example, a 10 percent primary density bonus for an LDR zoning district is a 10 percent increase in the four dwelling units per acre requirement:
A secondary density bonus of eight percent would be applied to the base density of the applicable zoning district. The primary and secondary density bonuses added to the base density would allow for 4.8 dwelling units per acre:
After applying the 4.72 toward the gross acreage of the planned development, the result is then rounded to the nearest whole number. For example, on a nine-acre site, the 4.72 density allowance times nine acres equals 42.48 or 42 dwelling units.
A secondary density bonus shall be based on the following:
1.
Additional Open Space – Maximum Credit, 10 Percent. One percent increase in density for each two percent of common open space above the required common open space identified in subsection (C)(1) of this section.
2.
Active Recreational Areas – Maximum Credit, Three Percent. One percent increase for each additional two percent of active common recreational area created.
3.
Public Space – Maximum Credit Equals Maximum Density. One percent increase for each one percent (gross land area) of open space dedication to the public. Dedications shall be located to allow for access and use by the public. The director shall consider whether to accept or deny a proposed dedication. Public space in a PRD may overlap with the minimum open space requirement or additional open space. A minimum open space dedication of one-half acre is required, except for the dedication of a pedestrian/bicycle trail. A voluntary agreement for payment in lieu of dedication (see Chapter 19.68 FMC) may replace all of the additional open space and up to 10 percent of the minimum open space, less open space which is required to be on site by other provisions of the FMC.
4.
Nonexclusive Pedestrian/Bicycle Trail Easement/Right-of-Way – Maximum Credit, Three Percent. One percent increase for each 250 linear feet of nonexclusive, improved and maintained pedestrian/bicycle trail easement or right-of-way. Pedestrian/bicycle trails shall be separated from rights-of-way and, to the greatest extent possible, vehicular circulation areas. The trail shall be located for access and use by the public. The city engineer shall consider whether to accept or deny a proposed easement or right-of-way dedication based on its functional value to the city. The pedestrian/bicycle trail easement or right-of-way may overlap with the PRD open space requirement or additional open space. The width of the easement or right-of-way shall be at least seven feet, with a reduction to five feet for sensitive area management tracts or wetland buffers. The trail shall be a minimum of four feet in width and constructed per the requirements of the city engineer.
5.
Alley Loading – Maximum Credit, Four Percent. One percent increase for each 25 percent of the total residential or commercial lots which are restricted to alley-only vehicular access. The restricted lots shall be properly identified on the planned development site plan or plat.
6.
Mixed Housing Types and Styles – Maximum Credit, Two Percent. PRD shall be greater than or equal to 10 acres. The submitted development plans or restrictive covenants shall ensure a significant mixture of housing types and/or styles throughout the PRD. The mixture of housing styles shall conform to an overall design concept within the development and shall be consistent with the surrounding community. The building design or architectural concept shall be prepared by a licensed architect.
